Hydraulic dredging is and most certainly will remain a primary
means of maintaining and improving ship channels and for land
reclamation in near-shore water. The study of which this thesis
describes a part is intended to develop a method of predetermining the
immediate disposition of sand spoils from hydraulic dredging...
Two digestibility trials using sheep were conducted to determine
the digestibility coefficients of a commercially processed NaOH treated
annual ryegrass straw cube. Comparisons were made with loose, chopped
ryegrass straw and a ryegrass straw cube processed with molasses as a
binder.
The NaOH cubed straw was produced by spraying a...
The classical chi-square goodness of fit test and the Neyman smooth tests are generalized for arbitrarily right-censored samples. The test statistics are shown to have limiting chi-square distributions under completely specified (simple) null hypotheses and random censorship. Limiting distributions of the generalized chi-square goodness of fit tests are also established...
Experimental streams constructed by the Weyerhaeuser Company,
Tacoma, Washington, at Kalama Springs, Washington, were used to observe
successional changes in the benthos. Community changes were observed
relative to experimental manipulations of light intensity and nitrate
concentration in two experiments. The development of benthic assemblages
was followed for 150 days after...
Given a sample from a population whose distribution belongs to a
parametric family we would like to make predictions on the outcome of
a statistic (generally the sample sum) of a future sample from the same
population. These predictions can be in the form of intervals with some
associated level...
When stratification is employed to reduce the variance of an
estimate of the population mean, and the population does not possess an
a priori partitioning, the degree of reduction provided is affected by
the method of allocation, by the number of strata, and by the choice of
the stratum boundaries....
